I Specification of Letters Patent.

Application filed December 14, 1914. Serial No. 877,138.

To all whom it may concern: 7

Be it known that 1, MICHAEL A. Dnorrcoon, a citizen of the United States, and a resident of Delphos, in the county of Van Wert and State of Ohio, have invented a certain new and useful Sheet-Registering .Mechanism; and I do hereby declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference .being had to the accompanying drawings, and to the characters of reference marked thereon, which form a' part of this specification.

This invention relates particularly to a mechanism for use in connection with printing presses for automatically registering sheets in cylinder gripping or picking-up position as they are successively fed to such position.

The object of my invention is the provision of a simple and efficient-mechanism of this character, which is automatically OPBI'", able, in properly timed relation to the feed ing of sheets to cylinder engaging position, to

effect an accurate registering of the sheets" with the customary front and side gages,

whereby to enhance the practicability and character commercial value of presses of the described, and the like. I

Further objects and advantages of the invention will be apparent from the following detailed description of the invention.

The invention is fully described in the following specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,-

Figure 1 is a side elevation of a portion of a printing press and themechanism embodying the invention in operative relation thereto. Fig. 2 is a plan view of a portion of a printing press and the registering mechanism with parts broken away- Fig. 3 is an enlarged section on the line at, m in Fig. 2. Fig. 4 is a perspective view of aportion of the registering mechanism. Figs. 5 and 6 are enlarged side and plan views. of a portion of the registering mechanism. Fig. 7 is a section on the line 3/ in Fig. 6. Fig. 8 is an enlarged perspective view of at: portion of the control means of the registering mechanism. Fig. 9 is an enlarged front elevation of a portion of the cylinder and the associated parts of the registering mechanism. Fig. 10 is a perspective view ofthe same, and Fig. 11 is a perspective view of one of the table fingers with which the front gages coact when lowered.

Referring to the drawings, 1 designates the frame of a printing press, 2 the customary platen cylinder, and 3 the table on which sheets 4 are successively advanced by hand or automatically in any suitable manner into position for their front edges to be engaged by the gripping fingers 5 of the cylinder at a redetermined point in a. revolution there- 0 ,as is well understood in theart. The advancing movements of a sheet are stopped by the customary-front gage fingers 6, 6, which are periodically raised in any suitable manner from sheet obstructing position.

7 designates the customary side registering block for the sheets, which block is mounted on the table 3 in position for a side edge of a sheet to register therewith when in proper cylinder engagmg position.

The cylinder 2 has one side of its periphery open or cut away to provide a peripheral recess 2 which recess is customaril present in cylinders of this character. ounted within the cylinder recess 2 lengthwise thereof and journaled at its ends in the respectivc end wallsof the cylinder is a rockshaft 8, which is provided at one end without the respective cylinder end with a bellcrank lever 9, one arm of which is provided with a roller lO -that rides on the periphery of a camll, while the other arm thereof has a rod 12 projecting therefrom and working freely through a guide lug 13, which is fixed to the cylinder end. it coiled comp-res sion spring 14. encircles-the rod 12 between the lug 13 and a stop shoulderffwhichgshoulder is provided on the rod adjacent to its inner end, said spring exerting pressure on the lever 9 in a direction to yieldihgly retain the roller 10 in contact with the cam periphery. The cam 11, loosely encircles the cylinder shaft 2, and is fixed to the adjacent frame side by ins, or in any other suitable manner, whereliy the cam is held stationary relative to the frame, and the roller 10 is Patented Sept. 5, 1916. i

permitted to revolve therearound as the cylinder revolves. The cam 11 is provided at a predetermined point on its periphery with a protuberant portion which causes a rocking of the lever 8 in first one direction and then the other at each revolution of the cylinder due to the roller 10 traveling onto and from said protuberant portion. I

Projecting from the shaft 8 at points within the cylinder recess 2, are, in the present instance, two rocker-arms 15, which are disposed in tangential relation, or substantially so, to a circle struck from the cylinder axis. Each arm 15 is pivotally connected at its outer end by a block 16, in the present instance, to a rod 17 which is disposed in radial relation to the cylinder and has its inner end working in a. registering radially-disposed guide-socket 18 in the core portion of the cylinder (see Figs. 3, 9 and 10). The rods 17 are fixed at their outer ends to a bar 19, which extends lengthwise of the cylinder within the recess 2. This bar carries one or more segmental sheet reg-- istering brushes 20, which, in the present instance, are two in number, with their bristles projecting outwardly relative to the cylinder and arranged in the form of an are or segment of the cylinder periphery. The brushes or registering elements 20 are adjustable lengthwise of the bar 19 to facilitate a placing of the same suit the size of the sheet being operated on.- It is evident that the brushes 20 will have inward and outward radial movements relative to the cylinder upon a rocking oi the shaft 8, and that with the present arrangement the brushes will be moved. to their or operative position when the roller 10 rides upon the protuberant portion of the cam 11, and will stand in retracted or inoperative position within the cylinder recess 2 when H the roller 10 is riding on the retracted or neutral portion of the cam 11. The outward throw of the brushes is suiiicient to place the outer edges of their bristles slightly beyond the peripheral line of the cylinder in position to have contact with the under side of the forward edge portion of a sheet 14: which is fed to front gage coacting position or substantially so, as shown in Fig. 8.

Rising from the side portions of the press frame 1 adjacent to the cylinder ends are bearing arms 21, 21 to each of which is pivoted an arm 22. The arms 22 are rigidly connected at their free ends by a bar 23 forn ing a handle to facilitate a swinging of the arms. Mounted at its ends in suitable bearings provided in the respective arms 22 in termediate the ends thereof is a shaft 24: which, when the arms 22 are swung to the rearward operative position shown in Fig. 3, stands over the cylinder 2. One end of the shaft 24 projects beyond the respec 22 and carries a gear 25 which. 3;;7

I through a pinion 27 with a small drive 28 that is mounted on the adjacent end of the cylinder shaft 2*.

A registering wheel 29 is mounted on the shaft 24 for each cylinder brush or register ing element 20, being secured to the shaft by a set-screw 30, which facilitates an adjustment of the wheel on the shaft to suit the position of the cylinder brush. Each wheel 29 is provided on its periphery in the present instance, with two segmental sets of brush bristles'31, which sets are arranged at opposite sides of the wheel axis and adapt ed to have peripheral coaction with the re spective brushes 20 of the cylinder when the cylinder and wheels 29 are being driven. The proportion of the gears in the train which connects the cylinder shaft to the brush wheel shaft 24 is such that the cylinder will revolve twice for each single revolution of the brush wheels 29. will thus be seen that the two brushes 31' of wheel 29 will coact with the respective cylinder brush 20 at alternate revolutions of the cylinder for the purpose hereinafter described. As the peripheral speed of the cylinder brushes 20 18 approximately four times greater than the speed of the wheel brushes 31, the wheel brushes are preferably made proportionally shorter than the cylinder brushes. The difierence in the speed of rotation of the brushes 20 21 causes slowing down of sheets as they move into contact with the front gages, thereby pre venting injury to the leading edges of sheet when striking the gages. lit will be noted that one of the brushes 31 (the lower one in Fig. 3) is longer than the other. The long brush 31 is the one which first has contact with sheet, as it is the front of this brush that is intended to coact with and to act slow down a sheet before the cylinder brush contacts therewith.

Tt preferable in practice to incline the bristles oi": the brushes rearward from radial lines of the respective brushes relative to the direction of rotation of the carrying parts, or in other words, toward an advancing sheet when the brushes are in sheet coacting position, indicated in Fig. 3. The bristles are thereby caused to have a greater retarding action on the advancing sheet when its forward edge moves into contact therewith than would be the case if bristles were disposed in true radial planes.

As the forward edge of a sheet advances between the coactinn' brushes 20 and Z? n ing" movement, if rapid, is fi st a ier oy yielding gripping and forward moving action of the coacting brushes. When the front edge of a sheet has been moved by the registering brushes into contact with the front gages 6 the brushes will then have sliding contact with the sheet, for, while the gripping action of the coacting brushes 1s sufficient to draw a sheet into front gage coacting position, it is not sufficient to cause a continued forward movment of the sheet the respective arms 22, whereby to limit the rearward swinging movements of said arms. A downward turning of the screws 32 permits a movement of the wheels 29 toward the cylinder.

Projecting forward from the front edge of the table 3 are a plurality of sheet sup- 1 porting fingers 33, with which the vfront gages 6 coact when lowered. as is customary 1n presses of this character. The fingers 33 project in position to enter between the cylinder and wheel brushes 20 and 31 when in coacting relation, and such fingers have their .free ends forked or longitudinally notched, as shown at 34, (Fig. 11) to permit the brush bristles to project therethrough when in .sheet gripping position. The provision of the forked fingers 33 for each set .of registering brushes steadies a sheet at the opposite sides of the points of gripping thereof by the brushes. The fingers 33 are adjustably carried at their inner ends by a bar 35 for adjustment transversely .of thetable to suitthe positions of the brush sets and'of the front gages 6. j

Rising, in the present instance, from each of opposite sides of the press-frame 1 at the rear of the table 3 is a standard 36 (one only being shown) having a bearing arm 37 projecting forward therefrom. A-frame 38 is pivotally carried at its rear'end by the bearing-arms 37 of therespective standards, and this frame carriesat its forward end the table 3-. When the table 3 is in operextends rearward from the forward edge;

portion of the table 3 to adjacent the respective standards 38, and are provided at their rear ends with upwardly angled arms 41 which are loosely carried .by a shaft 42 that is j ournaled at its ends in bearing arms 43 projecting from the respective standards 36 above the bearing arms 37 Each bar is provided at its forward end with a bracket-arm 44 projecting upward andfor- I portion thereof by a pair of transversely spaced bars 45 which bars coact with the arms 44 and side bars 40 to form a frame which is capable of being raised and lowered relative to the table 3 and its supporting frame, the raising and lowering .movements of said upper frame taking place about'the shaft 42 as an axis.

Mounted for sliding movements on the two bars'45, transversely of the table 3, is a slide head 46 which carries a pair of shaft parts or rocker members 47 and 48, the ends of which have bearings in the respective sides of the head 46, said rocker members 47 and 48 being disposed transverse to the sliding movements of the head 46 and spaced longitudinally of such movements.

Each of the members 47 and 48 have pairs of arms 49 and 50 projecting downward therefrom and pivotally attached at their lower ends to a block 51, whereby a rockingmovement inunison to the respective arms and ralsing and lowering swinging movementsto the block 51, which, during such movements,-is held inhorizontal posi- .tion by said arms, as is apparent by reference to thedrawings. The block 51 is carried between the arms of the respective pairs and is provided on its bottom surface with a yielding wiping member 52, which, in the present instance, is in the form of a brush, .the bristles of which project downward toward the table 3. A longitudinally movable rod 53 is disposed between the frame bars-45 in parallel relation thereto and has its ends slidingly mounted in the respective frame arms 44. This rod projects through the slide head 46, in the resent instance, below the rocker members 4 and 48 and between the arms 49 and 50 of each pair. A cross-arm 54 has its ends slidingly mounted on the respective frame bars 45 at one end of the slide head 46 and has a split part 55' projecting therefrom and embracing the slide rod to which it is-fixedly clamped by a screw 56, whereby the cross-arm is caused to have ,reciprocatory movements with the rod 53. A sleeve 57 projects from the opposite side of the cross-arm 54'to the brush or wiping element 52 relative to the table 3. Projecting upward from the rocker memwhich carries an adjustable stop-screw 61 beryl, in the present instance, is an arm 60 at its outer end in position for one end of such screw to have contact with a registering stop portion 62 of the head 46, whereby to stop the downward swinging movements of the arms 49 and 50 when the attached block 51 has been lowered a predetermined distance. When the rod 53 is moved'to efiect a lowering of the brush or wiping element 52 it is intended that the cross-arm 54 will first be moved thereby relative to the head 4:6 to effect a lowering of the wiper element 52 and that the head 46 shall not have movethatthe retarded movement of the head 4:6.

relative to the cross-arm 54 shall not take place until the wiper element 52 hasreached the limit of its lowering movement the head 46 is provided with a drag, which has sliding frictional contact with one of the frame bars 45, such drag, in the present instance, comprising a spring finger 63, which trails from one side of the head 46 and has its free end provided with a felt or other frictional part 2a in sliding contact with the frame bar, as shown in Figs. 4, 5 and 7. The unitary movement of the carrying and control parts for the wiper element 52 are toward the side sheet gage 7 and the downward swinging movements of the wiper element are also in the same direction.

One end of the reciprocatory rod 53 is pivotally connected, as at to one arm of abell-crank lever 66, which is pivoted for horizontal movements to a bracket arm 67 projecting from the adjacent-frame bar 40,

and has its opposite arm pivotally connected to a rod 68. This rod projects rearward through a guide block 69, which is pivotally carried by a bracket arm 70 projecting from the rear portion of the adjacent frame bar 40, and the rear end of the rod 68 is connected to the upright arm of a bell-crank lever 71 (see Figs. 1 and 8). The lever 71 is pivoted for vertical movements to the adjacent bearing-arm 37, as at 72, and hasone arm projecting forward from such pivot and forked at its free end to straddle a pin 73 on the lower end of a reciprocally movable thrust bar 74:. The bar 74 extends upward from its point of connection with the lever 71 and has its upper'end forked and straddling the shaft 42, whereby its reciprocatory movements are guided by said shaft. A cam 75 on the shaft 42, when to tating with said shaft, coacts with a roller 76 on the bar 74: to impart positive outward reciprocatory movements to the bar. A coiled contractile spring 77 connects the outer end portionlof the bar to a stationary the table and in pivotal connection w frame part, as for instance, the heari 48, and serves to urge the bar 1 shaft 42, whereby to hold the roller To contact with the periphery of the cam A coiled contractile spring 78 extends forward from the frame bracket 70 and is connected at its forward end with the rod 68, whereby to cooperate with the spring 7'? retain the parts in retracted position, i which position the wiper element 52 stunt, raised relative to the frame bars 45.

The shaft 42, in the present instance, car ries a sprocket-wheel 79, which has connec tion through a chain 80 with one of a pair of sprocket-wheels 81, which are mounted on a subjacent shaft 82, the other of said pair of sprocket wheels having chain connection with a sprocket-wheel 83 on the shaft 8-5- of the press. The shaft 8% also has drive connection with the cylinder 2 through gears 85 and 86.

Mounted in the surface of the table 3 helow the wiping element 52 is a sheet regist ing bar 87, which is reciprocally inov transversely of the table and has its top s face flush with the top surface of the ta The end of the bar 87, which is adjac o the end of the reciprocatory rod 53 a bracket-arm 89 projecting from one s bar of the lover table supporting frame and has an arm pro ecting inward to rod 90, which extends rearward theref through a pivotal guide-block 91, block is carried by a bracket arm 92 jecting' from the rear end portion of the adjacent side bar of the frame 38. The rear end of the rod 90, after projecting thron the guideblock 91, is connected to the down wardly projecting arm of a bell-crank low 93, which is loosely mounted on the ace pivot stud 9 1-, which is mounted in the i end of the adjacent bearing arm 3'? forms the supporting pivot for one sid of the frame 38. The lever 93 has a rearw projecting arm pivotally engaging the 73 on. the thrust bar 1 It is thus evide that reciprocatory movements of the bar 743: wili communicate rocking movements both levers 71 and 93 and cause simultaneous reciprocatcry movements to he impai l to the rod 53 and bar 87 through the spective intermediate connections, said nections being such as to impart like move ments to rod and bar. In other words, the connections between the bar 74; respective reciprocatory members 53 and are such, in the present instance, that outward movement of the bar 7 4 relative o the shaft 42 will impart like longitudin movements in unison to said 1 with theparts 45' and 87 in the manner 'shown-enables the table frame '38 andthe 1 upper frame 4045 with the I respective parts carried thereby to be independently I raised and lowered on their pivots without disconnecting the registering mechanism.

When the'ele'ment' 52 has been lowered into sheet coacting position the limit of movement of the cross-arm 54 relative to the head 7 connected cross-arms 54 relative-to the as- 46 will havefbeen reached so that-the head, cross-arm and associated registering element. 52 will then move together as a" unit a during the continued outward movement of.

the rod 53, with-the element 52 in engage ment withthe sheet in opposition to the bar 87 and moving at the same speed as said bar. The engagement of a sheet b the 'coacting registering elements 52 an '87; will cause a transverse shifting of the sheet into register with the side gage 7, and'whenthe sheet has been so moved the elements 52 and 87 will slide in engagement with the .sheet during the continued movement of I such elements. Upon a reversing of the rod; .53 the cross-arm 54' will first be moved out- "ward relative to the head- 46 to raise the element 52' from engagement with the sheet after which the associated parts will be returned as a unit to at -rest position. When the sheethas been released by theside registering means the cylinder brushes 20 will have completed a complete revolution with the cylinder and the wheels 29 a half revoa lution,' thus causing the cylinder brushes and the other set'of brushes to engagethej front edge of the sheet and move it into register'. with the front gages (ishould it have been moved out of register therewith by the action of the side registerin means. It

isthus evident that at one revo -ution ofthe A cylinder 2' its brushes 20 haveinitial sheet registering ooaction with, one set of, brushes 31 and that at the next revolution of-the cylinder-the brushes 2O thereof have final sheet registering coaction with the other set v of brushes 31,- thereby insuring-a perfect register *of -a sheet with the front gages after a'jmoving of the sheet into register -with the side gagel It will be understood that thecylinder brushes 20 normally stand retrated within the cylinder recess 2 and are moved outward into sheet coacting po-.

It is found in practice, however, that the best results are obtained by the use of brushes, as the bristles thereof are sufficientlyyieldable to prevent a tearing or injury of a sheet and to slide in contact therewith when thesheet has been moved to gage coacting position. It is also to be understood that my invention contemplates the use alone of either the cylinder registering elements 20 or the use of an upper set of registering elements 31, as in either case the wiping or frictional action of the elementsagainst the sheet surface will tend to advance the sheet into gage coacting position. It will be a preciated, however, that the engaging of a s eet by'opposed sets of brushes will effect a more positive advancing action of the sheet than if the sheet is engaged by .a brushing or wiping element at one side onlythereof.

I wish it understood that my invention is I not limited to any specific construction, ar-

rangement or form of the parts, as it is capable of numerous modifications without departing from the spirit thereof.
